The problem may be the printer driver. When the printer was installed, it most likely defaulted to the HP PCL driver and your program may be wanting to use Postscript.

If your operating system is XP or Vista, both PCL and Postscript drivers are included. Simply go into the "Add Printer" wizard and install the printer again using the Postscript driver. Then try your MATHTYPE program and see if the equations print correctly. If not, you probably need to talk to whoever wrote the program to see if there are program specific drivers for their software, or if only certain printers are supported.

You probably can best get support from the manufacturer of your printer. The above is not an equation that can be deciphered, it appears like a conditional clause that determines thow a part of the printing process will be carried out. You could add details such as make and model then it's meaning might be traceable elsewhere

Start by cleaning the Corona Wire. There will be a slider on the top of the Drum Unit. Slide it all the way to the other side and back to where the arrows meet and try your print again.
If this does not fix the problem replace the drum unit as the drum itself may be worn. The drums are rated to do 12,000 pages and it has probably done this. 12,000 pages equates to about 5-6 cartridges.

You have two variables on the question. That is the Speed of the Train and the actual Time taken.
So you shouold be have two equations to resolve the two variables.
Lets assume the speed to be x and the actual time in minutes to be y.
So the 1st equation,
If the train goes with the actual or the normal speed x the train reaches within the time y.
we know that speed = distance X Time
so X = Distance x Y or
Distance = X/Y ------- 1
Next the 2nd equation.
[{(12.5/100) x X} + X] = Distance x (y-20) or
Distnace = [{(12.5/100) x X} + X] / (y-20) ------ 2
Now you can equate 1 and 2 to get the results.

make sure your driver is correct for the printer and your os. go to the printer properties and print a test page . this will tell you if it is the driver verses your application. also go to the printer itself and print a config page from memory this will remove the pc from the equation and you will know if the print er is able to print verse it being a computer problem
